Currently, OpenClaw agents can only reply to existing messages (thread replies). They cannot initiate a new root message in a Slack channel and use it as a thread anchor for ongoing discussion.

Root Cause

Currently, OpenClaw agents can only reply to existing messages (thread replies). They cannot initiate a new root message in a Slack channel and use it as a thread anchor for ongoing discussion.

Code Example

[channel] "Processing: layout feedback" ← agent creates this
  └ Claw: Issue #12 created
  └ Kai: PR opened
  └ Claw: LGTM
  └ Kai: Merged

Summary

Currently, OpenClaw agents can only reply to existing messages (thread replies). They cannot initiate a new root message in a Slack channel and use it as a thread anchor for ongoing discussion.

Use Case

In a multi-agent Slack workflow (e.g., PM Agent + Dev Agent collaborating in a channel), agents should be able to:

  1. Automatically create a root message when starting work on a new task
  2. Route all subsequent discussion and status updates into that thread
  3. Keep the channel clean — one thread per task/topic

Example:

[channel] "Processing: layout feedback" ← agent creates this
  └ Claw: Issue #12 created
  └ Kai: PR opened
  └ Claw: LGTM
  └ Kai: Merged

Current Behavior

Agents can only reply using thread_ts of an existing message. There is no way for an agent to post a new root message and bind the session to it.

Proposed Behavior

  1. Allow agents to post a root message to a Slack channel and capture the returned ts
  2. Bind the session to that ts as thread_ts — so all subsequent messages go into the thread
  3. Optional: autoThread: true session config or a createThread tool action

Implementation Notes

sendSlackMessage in extensions/slack/ already supports thread_ts. Missing piece: a way for agents to initiate a root message and bind the session to its ts. Possibly a buildSlackThreadingToolContext enhancement for "create new thread" mode.

Priority

Medium — significantly improves multi-agent collaboration UX in Slack channels.

Fix Plan

To enable OpenClaw agents to initiate a new root message in a Slack channel, we need to enhance the sendSlackMessage function and buildSlackThreadingToolContext. Here are the steps:

  • Enhance sendSlackMessage to accept an optional createThread parameter.
  • If createThread is true, post a new root message to the Slack channel and capture the returned ts.
  • Bind the session to the returned ts as thread_ts.
  • Update buildSlackThreadingToolContext to support "create new thread" mode.

Example Code

// extensions/slack/sendSlackMessage.js
async function sendSlackMessage(message, options = {}) {
  const { createThread, threadTs } = options;
  const slackClient = getSlackClient();

  if (createThread) {
    const response = await slackClient.chat.postMessage({
      channel: message.channel,
      text: message.text,
    });
    const ts = response.ts;
    // Bind the session to the returned ts as thread_ts
    message.threadTs = ts;
  } else {
    // Existing behavior: reply to an existing message
    await slackClient.chat.postMessage({
      channel: message.channel,
      text: message.text,
      thread_ts: threadTs,
    });
  }
}

Verification

To verify the fix, test the following scenarios:

  • An agent creates a new root message in a Slack channel.
  • The agent's subsequent messages are posted in the same thread.
  • Multiple agents can collaborate in the same thread.

Extra Tips

  • Consider adding error handling for cases where the Slack API returns an error when creating a new thread.
  • Document the new createThread parameter in the sendSlackMessage function.
  • Test the fix in a staging environment before deploying to production.
